Description

Technical Field

[0001] The present application relates to the technical field of cosmetics, and more specifically, to an ultra-fine long-lasting skin-lightening air cushion cream and a preparation method thereof. Background Art

[0002] With the development of the economy, the pace of work and life is getting faster and faster. Coupled with the damage to the skin caused by many factors such as bad living habits, harsh environment, ultraviolet rays, improper skin care, etc., more and more people are troubled by a combination of skin problems such as dryness, roughness, inelasticity, dull skin tone, enlarged pores, dark circles, acne scars, etc.

[0003] To achieve a naturally radiant complexion and enhance their allure, more and more people are turning to foundation. Foundation's primary functions are to conceal blemishes, adjust skin tone, refine pores, and provide a barrier. However, foundation products aren't universally suitable for all skin types. Applying foundation to skin in poor condition often results in caked-on makeup, a lack of delicate texture, and a heavy, unnatural, artificial look. Furthermore, because human skin naturally secretes a certain amount of oil, this oil can dissolve some of the ingredients in foundation products, causing patchy, flaky, and inconsistent makeup. There are many products available for different skin types, including moisturizing foundations for dry skin. While these contain a high amount of oil, they appear natural when first applied, but their long-lasting properties are limited, with some not being rub-resistant. Furthermore, long-lasting foundations on the market can be prone to drying, flaking, and cakeiness.

[0004] Air cushion products, with their quick application and portable touch-up options, have become a core competitive force in the foundation makeup market, particularly favored by young consumers and professionals. With the evolution of beauty products, consumer demand for air cushions has shifted from single-purpose coverage to integrated beauty and skincare, seeking a multifunctional blend of high coverage, long-lasting makeup, a delicate finish, skin-nourishing ingredients, and eco-friendly design. However, most air cushion products on the market struggle to achieve both high coverage and a lightweight, delicate finish. Overuse can lead to a heavy, cakey look, failing to achieve a dewy, translucent, flawless, and newborn-soft finish. Summary of the Invention

[0005] In order to take into account high concealing power, delicate makeup effect, and creamy skin makeup effect, the present application provides an ultra-delicate long-lasting skin-brightening air cushion cream and a preparation method thereof.

[0006] In the first aspect, the present application provides an ultra-fine long-lasting makeup-brightening air cushion cream, which adopts the following technical solutions: An ultra-fine, long-lasting, skin-lightening air cushion cream comprises the following raw materials in percentage by weight: 8-32% volatile oil, 1-27% non-volatile oil, 0.5-4% emulsifier A, 0.5-2% emulsifier B, 0.1-16% film-forming agent, 0.1-3% functional raw material, 0.1-2% thickener, 0.01-12% color powder, 0.01-10% moisturizer, 0.5-1% emulsion stabilizer, 0.1-3% preservative, and 20-45% solvent; The volatile oil is selected from at least one of isododecane, cyclopentasiloxane, and methyl trimethicone; the non-volatile oil is selected from at least one of octyl methyl siloxane, methyl hydrogenated rosinate, trimethyl pentaphenyl trisiloxane, phenyl trimethicone, diphenylsiloxyphenyl trimethicone, and hydrogenated polydecene; The film-forming agent is selected from at least one of acrylates / polydimethylsiloxane copolymers, trimethylsiloxysilicate, acrylates / polytrimethylsiloxane methacrylate copolymers, polymethylsilsesquioxane, and VP / hexadecene copolymers.

[0007] By adopting the above technical solution, emulsifier A, emulsifier B and volatile oils, non-volatile oils, functional raw materials, colorants, film-forming agents, etc. are used as raw materials, and the weight percentage of each raw material is controlled within a certain range, which effectively promotes the interaction between the raw materials, so that the prepared air cushion cream has good stability, and can form a film on the skin that tightly locks the color powder, and has the dual effects of water resistance and oil resistance, reducing the migration of the air cushion cream, making the makeup long-lasting, soft and delicate, and effectively alleviating makeup oxidation. In addition, the use of high-refractive index oil compound can brighten the makeup face, and combined with a brightening film-forming agent, while being close to the skin and lasting, the product as a whole looks more shiny and moisturized.

[0008] The volatile oil used in this application is isododecane, etc. After being applied to the skin, it will evaporate rapidly to form a uniform, thin film on the skin, thereby reducing the contact of the air cushion cream with the external environment, reducing the risk of makeup removal due to sweat, oil secretion, etc., and enhancing the lasting effect of the air cushion cream. At the same time, the volatile oil will take away some of the heat on the skin surface when it evaporates, so that the skin has a refreshing and non-greasy feeling; while the non-volatile oil is a moisturizing oil with good moisturizing and hydrating properties. When used in combination with volatile oils, the non-volatile oil can form a moisturizing film to prevent skin moisture loss, thereby providing long-lasting moisturizing and preventing skin from becoming dry and mottled. At the same time, this moisturizing effect can also make the air cushion cream smoother on the skin, making the skin more hydrated and shiny. In addition, the viscosity of the air cushion cream can be adjusted to make its texture more delicate and uniform, and it can fill the gaps between the powders, reduce the agglomeration of the powders, and make the air cushion cream present a smoother and more delicate makeup effect on the skin.

[0009] Therefore, a combination of volatile and non-volatile oils is used. Volatile oils enhance makeup's longevity, while non-volatile oils provide a moisturizing effect. This not only maintains makeup's integrity for a long time, but also keeps the skin hydrated. This also addresses the drawback of simply emphasizing hydration, which can easily lead to makeup fading. The refreshing feel of volatile oils and the moisturizing feel of non-volatile oils complement each other, providing a more comfortable skin experience. Volatile oils quickly form a film, making makeup more adherent and long-lasting, while non-volatile oils improve texture, making the makeup look more delicate and natural. The synergistic effect of the two can create a high-quality makeup effect, making the skin appear smoother and flatter, better covering blemishes, and presenting a healthy and radiant skin.

[0010] In addition, acrylic acid (ester) / polydimethylsiloxysiloxane copolymers, trimethylsiloxysilicate, etc. are all brightening film-forming agents. The transparent film they form can lock in the skin's own moisture and the moisturizing ingredients in the formula. At the same time, their glossy properties make the skin look plump, elastic, and emit a healthy watery glow. When used with volatile oils and non-volatile oils, they can instantly fill in the texture, creating a silky, pore-invisible delicate skin feel, and can effectively lock in foundation products, resist sweat, oil and friction, and prolong the makeup's lasting time. The film-forming agent fixes the colorant particles on the skin and forms a continuous film. The volatile oil helps to spread evenly, and the non-volatile oil enhances flexibility, making the makeup highly integrated with the skin, looking like natural good skin.

[0011] Optionally, the mass ratio of the volatile oil to the non-volatile oil is 15-20:11.5.

[0012] By adopting the above technical solution, the dosage ratio of volatile essential oil to non-volatile essential oil is made more precise, so that the prepared air cushion cream has better makeup lastingness, moisturizing properties, and delicate smoothness.

[0013] Optionally, the volatile oil is cyclopentasiloxane, and the non-volatile oil includes octyl polymethylsiloxane, hydrogenated polydecene, and phenyl polytrimethoxysiloxane in a mass ratio of 3-4:4.5-5:4.

[0014] By adopting the above technical solution, cyclopentasiloxane is used as a volatile oil, which has extremely low surface tension and rapid volatility. It can spread and evaporate quickly on the skin surface, reduce the stickiness of the cushion cream, and form a uniform and dry preliminary film layer; octyl polymethicone has good lubricity and spreadability, hydrogenated polydecene has excellent moisturizing and hydrating properties, and phenyl polytrimethoxysiloxane has unique glossiness and good skin feel adjustment ability. When octyl polymethicone, hydrogenated polydecene and phenyl trimethoxysiloxane are mixed, the molecular structure of octyl polymethicone can be intertwined with the molecules of the other two oils, adjusting the viscosity and fluidity of the entire oil system, thereby increasing the ductility of the oil system, making the cushion cream easier to spread on the skin, less likely to clump or unevenly apply, and at the same time more silky and soft, forming a delicate and glossy film layer on the skin, improving the overall texture of the makeup.

[0015] When octyl polymethicone, hydrogenated polydecene, phenyl trimethoxysiloxane and cyclopentasiloxane are combined, the lubricating properties of octyl polymethicone can help cyclopentasiloxane spread more smoothly on the skin, further optimizing the skin feel of the cushion cream when applied, making it smoother. When hydrogenated polydecene is used with cyclopentasiloxane, hydrogenated polydecene can fill the gaps that may be caused by the expansion of cyclopentasiloxane, continuously provide moisture to the skin, and prevent the skin from being damaged by moisture. When phenyl trimethoxysiloxane is combined with cyclopentasiloxane, after cyclopentasiloxane evaporates and forms a film, phenyl trimethoxysiloxane can give the air cushion cream a certain gloss, making the skin look healthier and more radiant. Therefore, cyclopentasiloxane is used as the volatile oil, and a specific proportion of octyl polymethicone, hydrogenated polydecene and phenyl trimethoxysiloxane are used as non-volatile oils, which can make the air cushion cream have a long-lasting, moisturizing, delicate, natural, soft and smooth makeup feel.

[0016] Optionally, the film-forming agent includes trimethylsiloxysilicate and acrylic acid (ester) / polydimethylsiloxane copolymer in a mass ratio of 4:0.3-0.5.

[0017] By adopting the above technical solution, trimethylsiloxysilicate can form a tough and long-lasting film on the skin surface. The silicon-oxygen bond in its molecular structure gives the film good flexibility and adhesion, which can effectively block sweat and oil secretion, increase the makeup holding effect, and has good smoothness, increasing the comfort of application, so that the air cushion cream blends perfectly with the skin and makes the makeup appear natural and shiny. The acrylic acid (ester) part in the acrylic acid (ester) / polydimethylsiloxysiloxane copolymer structure has good film-forming properties and adhesion, and can be closely combined with the skin. , while the polydimethylsiloxane part gives the film a certain smoothness and breathability. The film formed by the combination of the two is not only strong, but also allows the skin to breathe, reducing problems such as acne caused by the non-breathable film layer, and the film layer fills into the fine lines on the skin surface, making the skin smoother and more delicate. When combined with trimethylsiloxysilicate, the film layers formed by the two complement each other, enhance the makeup lastingness, and make the film formed by the air cushion cream on the skin fit the skin better, further improving the delicateness and moisturizing degree of the makeup, creating a "natural skin" and "pseudo-bare face" effect.

[0018] Moreover, the film layer formed by trimethylsiloxysilicate and acrylic acid (ester) / polydimethylsiloxane copolymer can well wrap and fix the color powder, preventing the powder from scattering or gathering on the skin, making the makeup more uniform and lasting, while increasing the adhesion between the powder and the skin, improving the covering power and color rendering of the makeup. In addition, the components in the film-forming agent have good compatibility with oil ingredients such as cyclopentasiloxane and octyl polymethylsiloxane, and will not chemically react with the oil or produce stratification, and can form a stable dispensing system.

[0019] Optionally, the emulsifier A is selected from at least one of lauryl PEG-10 tris(trimethylsiloxy)silylethyl dimethicone, cetyl PEG / PPG-10 / 1 dimethicone, PEG-9 polydimethylsiloxyethyl dimethicone, PEG / PPG-18 / 18 dimethicone, and PEG-10 dimethicone; The emulsifier B is selected from at least one of polyglyceryl-4 isostearate, polyglyceryl-2 triisostearate, polyglyceryl-3 diisostearate, and polyglyceryl-2 isostearate.

[0020] By adopting the above technical solution, two different emulsifiers are used in the air cushion cream. Their synergistic use can construct a firmer and more stable emulsification system. Emulsifier A can form a stable protective film at the interface between the oil phase and the water phase, while emulsifier B enhances the affinity with the water phase. The two work together to tightly combine the oil droplets and water droplets, effectively preventing the emulsification system from stratification, demulsification, etc. during storage or use, ensuring the stable quality of the air cushion cream and maintaining the stability of the emulsification structure under different temperatures and different pH conditions.

[0021] In addition, emulsifiers A and B can increase the silky touch of the cushion cream, making it smoother and easier to spread. At the same time, they help to form a delicate and light texture, presenting a natural and light makeup effect, and enhance the skin's barrier function, maintain the skin's moisture balance, and increase the durability of the makeup effect.

[0022] Optionally, the emulsifier A comprises cetyl PEG / PPG-10 / 1 polydimethylsiloxane and lauryl PEG-10 tris(trimethylsiloxy)silylethyl polydimethylsiloxane in a mass ratio of 2.5:1-1.2.

[0023] By adopting the above technical solutions, both have good affinity for oil phase and water phase, can efficiently emulsify various types of oils and active ingredients, ensure that powders, oils and other ingredients are evenly dispersed in the formula, avoid stratification and precipitation, and at the same time make the emulsification system more delicate and uniform, making the air cushion cream more close to the skin and the makeup effect more natural; give the air cushion cream a lighter and more breathable texture, reduce the sense of heaviness, and use it with a film-forming agent to enhance the long-lasting makeup of the air cushion cream.

[0024] Optionally, the color powder includes a mixture of titanium dioxide, iron oxide yellow, iron oxide red and iron oxide black in mass ratios of 10.5%, 1%, 0.24% and 0.07%, and the titanium dioxide, iron oxide red, iron oxide black and iron oxide yellow are all pretreated with at least one of silica, polydimethylsiloxane, triethoxyoctylsilane, aluminum hydroxide and isopropyl titanium triisostearate.

[0025] By adopting the above technical solution, a mixture of titanium dioxide, yellow iron oxide, red iron oxide and black iron oxide is used to obtain color powder, which is then combined with emulsifiers, oils and other ingredients to form a stable system, which can fill fine pores and textures, make the skin smoother, and enhance the delicateness of the makeup. By adjusting the dosage, colors that are highly matched with different skin tones can be formulated. Titanium dioxide mainly plays a role in brightening and whitening, while iron oxide red, iron oxide black and iron oxide yellow can adjust the red, black and yellow tones of the color respectively, thereby simulating various natural skin colors. While covering blemishes, it retains the natural luster of the skin, making the makeup look more natural and transparent, as if the skin itself is in such a good condition, creating a "mom's skin" makeup effect.

[0026] Optionally, the titanium dioxide includes 1.2% by mass of titanium dioxide No. 1, 1.5% by mass of titanium dioxide No. 2 and 7.8% by mass of titanium dioxide No. 3, titanium dioxide No. 1 is pretreated with silica and polydimethylsiloxane, titanium dioxide No. 2 is pretreated with triethoxyoctylsilane and aluminum hydroxide, titanium dioxide No. 3 is pretreated with isopropyl titanium triisostearate and polydimethylsiloxane, iron oxide yellow is pretreated with isopropyl titanium triisostearate and polydimethylsiloxane, iron oxide red is pretreated with isopropyl titanium triisostearate and polydimethylsiloxane, and iron oxide black is pretreated with isopropyl titanium triisostearate and polydimethylsiloxane.

[0027] By adopting the above technical solution, the pretreatment of aluminum hydroxide can form a uniform coating layer on the surface of the toner, reduce the mutual attraction and aggregation between the toners, make it more evenly dispersed in the formula system, and not easily form lumps. Triethoxycaprylylsilane contains siloxane groups and organic functional groups, which can chemically react with active groups such as hydroxyl groups on the surface of the toner to form chemical bonds and modify the surface of the toner, making the toner more compatible with other ingredients in the formula, while reducing the surface energy of the toner, making the toner easier to wet and disperse in the medium. Polydimethylsiloxane makes the toner smoother when applied, reduces the friction between the toner and the skin, improves the comfort of use, and improves the gloss, presenting a delicate and smooth touch. Isopropyl titanium triisostearate has certain antioxidant and light stability, which can protect the toner from external environmental factors, prevent the toner from color change or degradation due to oxidation or light, and at the same time increase the adhesion between the toner and the skin, thereby extending the shelf life of the product and the durability of the makeup.

[0028] Optionally, the moisturizing agent is selected from at least two of glycerin, erythritol, panthenol, butylene glycol, maltose, maltitol, 1,3-propylene glycol, etc.; The preservative is selected from at least two of caprylyl glycol, p-hydroxyacetophenone, ethylhexylglycerin, 1,2-hexanediol, etc.; The thickener is selected from at least one of disteardimethylammonium hectorite, quaternary ammonium salt-18 bentonite, and silica dimethyl silylate; The emulsion stabilizer is at least one of sodium chloride and magnesium sulfate.

[0029] By adopting the above technical solution and using ingredients such as glycerin and erythritol as moisturizers, the skin can be continuously replenished with moisture, the moisturizing degree of the air cushion cream can be increased, and the skin can be softer and smoother; while preservatives can prevent the product from being contaminated by microorganisms during storage and use, thereby extending the shelf life of the product and ensuring the quality and safety of the product; sodium chloride and magnesium sulfate can adjust the physical properties of the system, so that the air cushion cream maintains a uniform state, increases thixotropy, has better spreadability and ductility when applied, and makes the makeup more stable.

[0030] Optionally, the moisturizing agent comprises maltose, maltitol, erythritol, butylene glycol and panthenol in a mass ratio of 0.375:0.125:1:7:0.3; The preservatives include caprylyl glycol, ethylhexylglycerin and 1,2-hexanediol in a mass ratio of 0.2:0.1:0.5.

[0031] By adopting the above technical solution, maltose, maltitol, erythritol and butylene glycol cooperate with each other to provide moisturizing to the skin from different angles and levels, forming a multi-level moisturizing network. From the surface of the skin to the deep layer, sufficient moisture can be obtained, so that the skin remains hydrated and plump, greatly improving the moisturizing effect and durability. Moreover, the texture and skin feel of different moisturizers are different. The combination of the above moisturizers makes the air cushion cream have good moisturizing effect without being greasy, thick or dry, and the skin feel is more comfortable.

[0032] Caprylyl glycol has antiseptic and antibacterial effects, and also has certain moisturizing and natural effects. It is low in irritation and has little irritation to the skin. It is suitable for people of all skin types, especially those with sensitive skin. Ethylhexylglycerin can enhance the activity of other preservatives, improve the antiseptic effect, and improve the skin feel of the product, making the product smoother and easier to apply. The combination of caprylyl glycol, ethylhexylglycerin and 1,2-hexanediol can expand the antibacterial spectrum and has a good inhibitory effect on a variety of bacteria and molds.

[0033] Optionally, the functional raw material is selected from at least one of polydimethylsiloxane / vinyl polydimethylsiloxane crosspolymer, polydimethylsiloxane crosspolymer, polysilicone-11, polydimethylsiloxane, cyclopentasiloxane, silica, synthetic fluorphlogopite, polymethylsilsesquioxane, boron nitride, and methyl methacrylate crosspolymer.

[0034] By adopting the above technical solution, the above raw materials are used as functional raw materials, which can make the air cushion cream as smooth as silk during the application process, without the phenomenon of powder sticking, thereby improving the comfort of use. At the same time, after application, the skin feels refreshed and breathable, and has a delicate and smooth touch, creating a natural and flawless makeup effect. At the same time, it has a good concealing effect, evens out skin tone, and makes the skin look whiter, brighter and more lustrous.

[0035] Optionally, the functional raw material includes a mixture of synthetic fluorphlogopite and polysilicone-11, polydimethylsiloxane, and cyclopentasiloxane in a mass ratio of 1-1.5:1.5, and the mass percentages of polysilicone-11, polydimethylsiloxane, and cyclopentasiloxane are 14-16%:45-47%:37-40%.

[0036] By adopting the above technical solution, synthetic fluorphlogopite has a unique pearlescent effect, which can reflect light at different angles, adding a natural luster to the skin. At the same time, it has a certain covering ability, can fill the pores and fine lines on the skin surface, and reduce blemishes. Polydimethylsiloxane and cyclopentasiloxane have lubricating properties, which can make the skin have a more uniform and smooth texture. Polysilicone-11 can form a fluffy texture, making the air cushion cream lighter and thinner. Therefore, the use of polysiloxane compounds and synthetic fluorphlogopite as functional raw materials can reduce the occurrence of makeup coming off, make makeup more lasting, make the skin feel softer and smoother, improve skin touch, lock in skin moisture, and relieve skin dryness.

[0037] Optionally, in the mixture of polysilicone-11, polydimethicone and cyclopentasiloxane, the proportion of polysilicone-11 is 14-16%, the proportion of polydimethicone is 45-50%, and the proportion of cyclopentasiloxane is 36-42%.

[0038] In a second aspect, the present application provides a method for preparing an ultra-fine long-lasting skin-lightening air cushion cream, which adopts the following technical solution: A method for preparing an ultra-fine long-lasting skin-lightening air cushion cream comprises the following steps: Mix 60-65% of the non-volatile oil with the volatile oil, film-forming agent, thickener and 1 / 2 of the functional raw materials at 25-35°C and stir for 2-6 minutes to prepare phase A; Emulsifier A, emulsifier B and the remaining functional raw materials are mixed evenly to prepare phase B; Mix the color powder and the remaining non-volatile oil evenly to prepare phase C; Mix the moisturizer, emulsion stabilizer, preservative and solvent and stir for 3-8 minutes at 25-35°C to prepare phase D; Grind the phase C raw material 2-3 times, add phase B to phase A at 25-35°C, stir for 2-6 minutes, then add phase C at 25-35°C, homogenize for 6-10 minutes, and then add phase D dropwise thereto while homogenizing at a speed of 5000-6000 rpm for 2-4 minutes. After the addition is completed, increase the homogenization speed to 5500-6500 rpm and homogenize for 2-4 minutes to prepare an air cushion cream.

[0039] By adopting the above technical solution, the formula raw materials are divided into different phases and added to the system step by step, which helps to promote the interaction between the raw materials and improve the stability of the air cushion cream. In addition, the color powder is ground so that the color powder can be better integrated with the oil phase, making the product more delicate, fit, clear and natural. By controlling various process parameters, the anti-migration property of the air cushion cream is effectively improved, achieving a long-lasting and non-dull makeup effect and a soft and delicate skin feel. The preparation method of this application, The process is simple, low in cost, suitable for industrial production, and has broad market prospects.

[0040] In summary, this application has the following beneficial effects: 1. Since the present application adopts the combination of non-volatile oils and volatile oils, it can not only keep the makeup intact for a long time, but also keep the skin moisturized, avoiding the problem of skin dryness caused by simply pursuing long-lasting makeup, but also solving the disadvantage of simply emphasizing moisture and easy makeup removal, and can also make the makeup more adherent, long-lasting, smooth, flat, delicate and natural; the use of brightening film-forming agents in combination with volatile oils can bring a light touch, promote film formation, and enhance delicate silkiness; in combination with non-volatile oils, it can provide a moisturizing feeling, significantly enhance glossiness, improve hydration and film flexibility; therefore, the synergistic effect of non-volatile oils, volatile oils and film-forming agents has the final effect of making the skin extremely delicate, smooth, long-lasting, and with a healthy and moist luster.

[0041] 2. In this application, trimethylsiloxysilicate and acrylate / polydimethylsiloxane copolymer are preferably used as film-forming agents, and are used in combination with volatile oil cyclopentasiloxane, non-volatile oil octyl polymethylsiloxane, hydrogenated polydecene and phenyl polytrimethoxysiloxane to make the air cushion cream more evenly and smoothly applied, and the makeup look more delicate, natural and long-lasting, creating a "pseudo-bare face" and "mother's skin" makeup effect.

[0042] 3. In this application, a compound of titanium dioxide, red iron oxide, black iron oxide and yellow iron oxide is used as a color powder, and the color powder is coated with triethoxycaprylylsiloxane and isopropyl titanium triisostearate, which can improve the dispersibility of the color powder, increase the smoothness and uniformity of the air cushion cream when applied, improve the uniformity of the makeup gloss, and make the makeup more coordinated and beautiful. In addition, when preparing the air cushion cream, the color powder is pre-ground 2-3 times so that the color powder can better blend with the oil phase, obtaining a more delicate, fitting, clear and natural makeup.

[0055] Comparative Example Comparative Example 1: An ultra-fine long-lasting skin-lightening air cushion cream, which differs from Example 1 in that the raw materials of Phase C are not ground.

[0056] Comparative Example 2: An ultra-fine long-lasting skin-lightening air cushion cream, which differs from Example 1 in that, in phase A, an equal amount of octyl polymethylsiloxane is used instead of the volatile oil cyclopentasiloxane.

[0057] Comparative Example 3: An ultra-fine long-lasting skin-lightening air cushion cream, which differs from Example 1 in that the film-forming agent in phase A is polyurethane-15.

[0058] Performance testing An air cushion cream was prepared according to the methods in the examples and comparative examples, and performance tests were performed according to the following methods. The test results are recorded in Table 2.

[0059] 1. Heat resistance: Place the cushion cream at (40±1)℃ for 24 hours. After returning to room temperature, test the oil permeability of the cushion cream. For specific testing methods, refer to QB / T1857-2013 "Moisturizing Creams".

[0060] 2. Cold resistance: Place the air cushion cream in an environment of (-8±2)℃ for 24 hours. After returning to room temperature, compare the shape with that before the test.

[0061] 3. Anti-migration performance: Use a dropper to dispense 0.30g of the cushion cream (total amount) onto the skin of the human arm, spread it evenly, and let it dry naturally for 5 minutes. Use a paper towel to press the three areas with the same force. Use an analytical balance to measure the weight increase (the amount of foundation migration) of the three paper towels. Migration rate = migration amount / total amount × 100%. Test five skin specimens in each group and take the average of the test results.

[0062] 4. Skin feel test: Female volunteers aged 20-50 with healthy skin were selected for the experience test and divided into 10 groups with 20 people in each group. The cushion creams prepared in Examples 1-7 and Comparative Examples 1-3 were scored. After simple cleaning and skin care in an environment with a temperature of 26±1°C and an air humidity of about 75%, different samples were used and the skin feel was evaluated at (1.0±0.1) mg / cm 2Apply the test product to your face. After using it, rate the product's moisturizing, smoothness, skin-fitting, and concealing power on a 10-point scale, with 10 being the best experience, 9 being the second best, and 1 being the worst.

[0063] Table 2 Performance test results of air cushion cream From the comparison of the data in Table 2, it can be seen that the air cushion cream prepared by using the raw material dosages in Examples 1-3 has a good skin feel, a moisturizing feel, is adhered to the skin and easy to spread, and can maintain makeup and moisturize for a long time. The present application uses acrylic acid (ester) / polydimethylsiloxane copolymer and trimethylsiloxysilicate in a certain proportion as a film-forming agent, hydrogenated polydecene, octyl polymethylsiloxane and phenyl polytrimethicone as non-volatile oils, cyclopentasiloxane as a volatile oil, and a certain amount of emulsifier A and emulsifier B, so that the air cushion cream has high makeup lastingness, high skin adhesion and high moisturizing effect.

[0064] Compared with Example 1, in Example 4, trimethylsiloxysilicate is used as a film-forming agent. It can be seen that the mobility of the air cushion cream increases, the makeup holding ability decreases, and the smoothness and adherence are weakened. In Example 5, the mixture of polysilicone-11, polydimethylsiloxane and cyclopentasiloxane is not added to phase A, and only synthetic fluorphlogopite is added to phase B. It can be seen that although the air cushion cream has good concealing power, its skin adhesion, smoothness and moisturizing feel scores are significantly reduced, the skin feel deteriorates, and the mobility is increased, and the makeup holding ability is weakened.

[0065] In Example 6, compared with Example 1, an equal amount of octyl polymethicone is used to replace hydrogenated polydecene, that is, the non-volatile oil contains only octyl polymethicone and phenyl trimethicone. It can be seen that the moisturizing and humectant properties of the air cushion cream are reduced, the makeup holding effect is worse, and the smooth spreading effect is reduced.

[0066] In Example 7, compared with Example 1, an equal amount of lauryl PEG-10 tris(trimethylsiloxy)silylethyl polydimethicone is used in phase B to replace cetyl PEG / PPG-10 / 1 polydimethicone, that is, the emulsifier A is all lauryl PEG-10 tris(trimethylsiloxy)silylethyl polydimethicone. It can be seen that the moisturizing, smooth feeling and skin-fitting properties of the prepared air cushion cream are reduced, the oil permeation rate is increased, and the heat resistance is weakened.

[0067] Compared with Example 1, the raw materials of phase C in Comparative Example 1 were not ground, and the cushion cream prepared therefrom was not fine enough. Figure 1 , it can be seen that its spreadability and fineness are not as good as this application, and its compliance and moisturizing properties are also not well evaluated.

[0068] In Comparative Example 2, an equal amount of non-volatile oil octyl polymethylsiloxane was used to replace the volatile oil cyclopentasiloxane. Compared with Example 1, the air cushion cream made without adding volatile oil had a lower score in terms of fit and smoothness, and its migration rate increased, resulting in a poorer makeup-lasting effect, but better moisturizing effect.

[0069] Compared with Example 1, in Comparative Example 3, polyurethane-15 is used as a film-forming agent. It can be seen that the mobility of the prepared cushion cream increases, the scores of moisturizing degree and smoothness decrease, and the skin feel becomes worse.

[0070] Real-person testing of the air cushion cream's concealing power and long-lasting makeup effect: (1) Test subjects: Two volunteers were selected. The volunteers were required to be in good health, have no history of skin diseases or allergies, and had not used any products that might affect the skin condition or test results within one week before the test.

[0071] (2) Testing tools: Select Example 1 as the test cushion cream sample, and prepare a pen with bright and long-lasting color, such as purple, to simulate blemishes on the face.

[0072] (3) Test environment: The test was carried out in a constant temperature and humidity environment with a temperature of 22±2°C and a relative humidity of 50±5%.

[0073] (4) Test process: Have the volunteers clean their faces and wipe them dry. Use a colored pen to place test points on designated areas of the volunteer's face (such as cheeks and nose). Each test point is about 3-5mm in diameter and has a moderate color depth, so as to clearly simulate common blemishes. Before applying the air cushion cream, use a high-definition camera to take clear photos of the simulated blemishes on the volunteer's face as a record of the initial state. Have the volunteers follow their daily usage habits and use the puff that comes with the air cushion cream to dip an appropriate amount of product and evenly apply it on the face, including the area of ​​simulated blemishes. After the 8-hour test time is over, use a high-definition camera to take photos of the volunteer's face as a record of the final state. Volunteers can carry out their daily activities normally during the test, but should avoid strenuous exercise and long-term exposure to high temperature or humid environments to reduce the interference of external factors on the test results. The comparison of test case 1 before makeup and 8 hours after makeup is as follows: Figure 2 As shown, the comparison of test case 2 before makeup and 8 hours after makeup is as follows Figure 3 shown.

[0074] It can be seen that the air cushion cream prepared in Example 1 still has a good concealing effect 8 hours after application, has good durability and adherence, and does not cause drying out, powder sticking, etc.
